You don't need any harness if you are going to do just the alternator. Just the plug if that. There is a few writeups on this somewhere on this forum and RX7club.com and Teamfc3s.org

To summarize this.

Thick wire goes to battery which is the same as 85, in the 90 alternator one is for acc/starter which is like the 85 and the other one is recommended to get wired straight to the + side of the battery terminal. I have this configuration on my RX-3 and 79 RX-7 with no problems.......

yeah, i figured i just needed the plug.

thanks for the tips jerry

as for the s4, i don't know if there are some minor variances between the two(?).

i'm still quite a bit of a newb at most of this
